FELL GAUGE non LOOMS.

Application filed nine 24, 1924. Serial No. 722,144.

My saidinveution relates to a tell gauge'for looms and it is an object of the same to provide a device of this character in which the degree of tensionshall be indicated by a flexible'scale. Devices of this character are used in looms to indicate'the tensionof the cloth where, iorexample, the same has been loosened for repair 1ng afault'in weaving orfor tying'jbrokenj WVhen the cloth has warp ends orthe like. now been pulled downby the sand roll anele mentof the fell gauge is engagedwith the fell of the cloth to-operate the "fell gauge and indi-'= catevery accurately when the cloth has been pulled tight enough for theresumption of weaving.

Afnrther object of the inventionis-to'prd vide means in connectionwith a device-0t the character described-whereby a fault in'the position of the fell of the cloth shallbe indicated on the fell gauge on an enlarged scale,

Referring to the accompanying drawings,- whlchare made a part hereof and onwhich" similar reference characters indicate similar parts,

Figure 1 is a plan ofmy device-in operative Figure 6,:a :bottom plan of the-removable cover of thecasing for the gearing.-

In the drawings reference character iiidicatesa support for the-device which con-' nectedin any convenient manner to'the frame ofthe loom atone side of the forming fabric,

it beingshown as held in placeibysorews. 1 The support has a bearing inwhicha bracket 11' is securechsaid:bracket being-adj ustablyheldby set-screws 12't0 permit the operative elements of the fell gauge to ,be properly positionedrelative to'the width ofthe cloth: Thetop 01 the bracket is preferably-flattened to enable' the set-screws tofix the bracket incorrect po sition. Y

At the freeend of the bracket a base or bottommember 13 of a casing-is rigidly secured to the bracket. Saidbasemembersupportsa post l ipreferably in the form 015 a screw having threaded engagement with the base and this post holds a cap 15 in place'on the bottom.

Betweeirthe cap and the base a chamber'is provided 1I1'Wl110l1 a colled spring 16 is located,

saidspring being secured at one end to the cap as indicated at 17 and at the other end to a collar 18 held between a plate 19 and ashoulder on a pinion 25 as indicated at 20 in Figure 3, said collar havinga hollow neck extending" up-into the central opening in plate 19.

The plate 19lies close to the cap which is numerals as indicated in Figure 5 and also has a hair line indicated at 2 1, Figured The sleeve has gear teethblow'the collar' 18 and'said sleeve is'held to the base by means ofa shoulder on the screw 14. It will be un' f derstood that the constructionof these pal-ts may be'varied to suit manufacturing conditions,e.g., collar 18 might be formed integral with plate 19 or sleeve 25, etc, and the scale may be formed onthe uppersurface of the plate '19 if. desired. A, rack bar '26 extends through the casing'al'ongside the pinion 25" said bar having teeth to mesh with those of the pinion, Atits rear-end therack bar'has a yoke 27 adj ustably' secured thereto by means of nuts" 28. A flat bar 29 or other suitable carrier is f pivota'lly secured to the yoke by a pin 30an'd said bar extendsforward beyondfthe en'dof the bar 26 and'over a pair otcloth roll's'tO, 11.

to a position adjacent th'e'fell of the cloth as indicated in Figure 1. At its forward end the flat bar carries a comb 31 which may be in' one piece but-is here shown as having separate claws 32bent at theirextreme ends in a man-' ner to enable them to project down between the warps adj acentthe tell of the cloth.

The cap 15 "has oppositely positioned notches at 33 and to receive the bar 26 and smaller notches to receive the end"36"of 1 a deteut 37 having a thumb-piece 38. As will be seen from Figures 1 and 2 'the'thumb piece is above the base, the body'of the de-" tent is below the base andthe end 36 projects through the samefor engagement with. the

notches 3501 the cap. By this arrangement the bars26 and 29 maybe normally turned provided with an arcuate slot 21 closed by 'a transparent window of glass or celluloid and" asheet 22 is supported between the plate and the top of the cap said sheet carrying reference having a scale mark in the form of a hair line indicated at 23, said sheet being securelyfastened to plate '19.- The transparent window to a position at right angles to that of Figure 1 where the comb 8l'lies adjacent to bar 11 and distant from the fell of the cloth untilthe device is needed to perform the function hereinafter described. When the cloth has been wound back from the cloth beam and the defects in the weavin etc., have been corrected the thumb-piece 38 may be depressed to release detent 36 and the cap 15 with the bars 26 and 29 and other parts may be turned to the position indicated in Figure 1 with the ends of the comb teeth projecting between the warp threads to a point below the fell of the cloth. The warp being now rewound the fell will pull the bar 29 rearward carrying with it the bar 26 and rotating the pinion 25 by its engagement with the rack bar whereupon the scale marks will pass successively beneath the window 21 until the hair line 23 registers with the hair line 2 1.

It will be noted that the device by means of the hair lines indicates the posit-ion of the fell very accurately and that by reason of the relation of gearing in the casing the travel of the indicating sheet 22 is much greater than the movement of the fell thus making for accuracy in the indication of position of the fell relative to the loom.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spiritof the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims. 7

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:
